For example, if the prepared biogas slurry organic fertilizer is directly applied to farmlands, the hydraulic retention time of biogas slurry in an acidification tank can be shortened; if the prepared biogas slurry organic fertilizer is used for soilless culture, the organic matters remained in the biogas slurry are completely decomposed into micromolecular substances, and the hydraulic retention time of the biogas slurry in the acidification tank is longer, such as 3 hours; if the prepared biogas slurry organic fertilizer is used for field water and fertilizer sprinkling irrigation, particles in biogas slurry need to be thoroughly removed, and the hydraulic retention time of the biogas slurry in the acidification tank is longer, such as 4 hours. Typically, the hydraulic retention time in the acidification tank 3 is set to 2-4h, and the pH in the acidification tank is adjusted to between 6-8. Then, the hydrolyzed and acidified biogas slurry is subjected to depth filtration in a baffling precipitation tower 4, for example, particles in the biogas slurry are further removed after the biogas slurry is filtered by three screens of 60 meshes, 40 meshes and 20 meshes in the baffling precipitation tower 4, and the particles larger than or equal to 0.25mm in the biogas slurry can be filtered in the depth filtration process. And pumping the deeply filtered biogas slurry into a sand filter tank 5 through a pipeline 9 and a pump 11, wherein the water inlet pressure of the sand filter tank 5 is more than or equal to 0.4Mpa, the backwashing water inlet pressure is more than or equal to 0.20Mpa, and the deeply filtered biogas slurry further intercepts and adsorbs fine particles, colloids and organic matters which are not filtered in the deep filtering process through the sand filter tank 5. Then, pumping the finely filtered biogas slurry into a reaction kettle 6 through a pump 11, controlling the temperature and the pH to be proper, adding major elements of nitrogen, phosphorus and potassium, trace elements of iron, manganese, zinc and the like and other nutrient substances as exogenous nutrient substances, and compounding and complexing the exogenous nutrient substances with nutrient components in the biogas slurry, wherein the biogas slurry organic fertilizer meeting the growth requirements of different crops can be prepared by regulating and controlling the adding proportion, the reaction conditions and the like of each exogenous nutrient substance in the process. Generally, the temperature in the reaction kettle 6 is controlled between 35 ℃ and 45 ℃ during the reaction, and the pH is adjusted between 5.5 and 6.8 after the reaction. Finally, filtering particulate matters in a product generated by the reaction through a security filter 7 to remove insoluble matters. Wherein, the operating pressure of the cartridge filter 7 is more than or equal to 0.1 Mpa. So far, the recycled biogas slurry is prepared and sent into a finished product tank 8 through a pipeline. Finally, the recycled biogas slurry can be subjected to filling pretreatment, so that different filling, transportation and application requirements can be met. For example, before filling, 0.003% of sorbitan-80 as a stabilizer may be added, followed by concentration by reverse osmosis or dilution with water. Wherein, the recycled biogas slurry can be used as a compound fertilizer for filling and selling, and also can be sent into an irrigation system for field water-fertilizer integration and the like.
It will be understood that the above embodiments are merely exemplary embodiments taken to illustrate the principles of the present invention, which is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
